Safety Notice

Review the following safety precautions carefully before operating
the instrument to avoid any personal injuries or damages to the
instrument and any products connected to it.

The instrument should be serviced by qualified personnel
only.
Avoid Fire or Personal Injury.
Use Proper Power Cord. Use the power cord designed for the

instrument as authorized in your country only.
Ground the Instrument. The instrument is grounded through t he
grounding conductor of the po wer cor d. To avoid electr ic s hock th e
instrument grounding conductor(s) must be grounded properly
before making connections to the input or output terminals of the
instrument.
Observe all Terminal Ratings. To avoid f ire or shock hazard,
observe all ratings and marks on the instrument. Follow the user’s
guide for further ratings information before making connections to
the instrument.
Do not Operate Without Covers. Do not operate the instrument
with covers or panels removed.
Use Proper Fuse. Use the fuse of th e type, voltage and current
ratings as specified for the instrument.
Avoid Circuit or Wire Exposure. Do not touch exposed
connections and components when power is on.
Do not Operate With Suspected Failures. If suspected damage
occurs with the instrument, have it inspected by qualified service
personnel before further operations.

Do not Operate in Wet/Damp Conditions.
Do not Operate in an Explosive atmosphere.
Keep Product Surfaces Clean and Dry.

The disturbance test o f all the models meet the limit values
of A in the standard of EN 61326: 1997+A1+A2+A3, but
can’t meet th e limit values of B.

Input Terminal Protection Limitation

Protection limitation is def ined for the input terminal:

1． Main input (HI and LO) terminal

HI and LO terminals are used for Voltage, Resistance,

Capacitance, Continuity, Frequency and Diodes measurement.
Two protection limitations are defined:

1) HI-LO protection limitation: 1000VDC or 750VAC. It is the
maximum measurable voltage. The limitation can be

II

expressed as 1000Vpk.

2) LO-ground protection limitation. LO terminal can safely
“float” 500Vpk r el ati ve to the ground.

The maximum protection limitation of HI terminal relative to
the ground is 1000Vpk. Therefore, the sum of the “float”
voltage and the measured voltage cannot exceed 1000Vpk.

2． Sampling (HI Sense and LO Sense) termina l

HI Sense and LO Sense are used for 4-Wire Resistance

Measurement. Two protection limitations are defined:

1) HI Sense-LO Sense protection limitation: 200Vpk.

2) LO Sense-LO protection limitation: 2Vpk.

3． Current input (I) terminal

I and LO terminal are used for current measurement. The

maximum current which go through the I terminal is limited to
10A by the fuse on the rear panel.

NOTE: Voltage on the current input terminal corresponds to voltage
on LO terminal. To obtain favorable protection, specified fuse
should be used.

IEC Measurement Category II Overvoltage Protection

To protect against the danger of electric shock, DM3058/DM3058E
provides overvoltage protection for line-voltage mains connections
meeting both of the following conditions:
1． The HI and LO input terminals are connected to the mains

under Measurement Category II conditions, defined below.

2． The mains are limited to a maximum line voltage of 600VAC.
WARNING: IEC Measurement Category II includes electrical

devices connected to mains at an outlet on a branch circuit. Such
devices include most small appliances, test equipment, and other
devices that plug into a branch outlet or socket.
DM3058/DM3058E may be used to make measurements with the HI
and LO inputs connected to mains in such devices (up to 600VAC),
or to the branch outlet itself. However, DM3058/DM3058E m ay not
be used with its HI and LO inputs connected to mains in
permanently installed electrical devices such as the main
circuit-breaker panel, sub-panel disconnected boxes, or
permanently wired motors. Such devices and circuits are subject to
overvoltage that may exceed the protection limits of
DM3058/DM3058E.

：Voltag es above 600VAC may be measured only in circuits

NOTE

that are isol ate d fro m mai ns . H owe ve r, t rans ie nt ov ervo lta ge is also
present on circuits that are isolated from mains. DM3058/DM3058E
is designed to safely withstand occasional transient overvoltage up
to 4000Vpk. Do not use this equipment to measure circuits where
transient overvoltage could exceed this level.
